I’m a little lost. I activated the person notifications but no notices. Also I see that I need an SD card to have play back? What happens when SD card full?
There are two places to insure notifications are on. In the camera area, tap the Cog settings, then Notifications. Turn on Send Notifications. Also, set it for Persons (and Sound and Motion if you want). Then, you need to make sure the “bell” does not have a slash through it on the home tab of the app.
The oldest files will get overwritten. Depending on how big the SD card is, and what resolution you record at, this could be many days worth.
